Calculate the value of A. A= (E_1,2)/(2E_(2,1))Where E_(n,z) = Energy of electron in n^(th) orbit , Z = atomic number of hydrogen like specie.

Calculate the value of A. A= (E_1,2)/(2E_(2,1))Where E_(n,z) = Energy

1.	Calculate the value of A. A= (E_1,2)/(2E_(2,1))Where E_(n,z) = Energy of electron in n^(th) orbit , Z = atomic number of hydrogen like specie.
Answer» SOLUTION :`A= (E_(1,2))/(2E_(2,1)) = (-13.6 xx 2^2 xx 2^2)/( 2XX 1^2 xx (-13.6)xx 1^2)= 16/(2) = 8`
